以2，7，9，10-四溴芘-4，5-二酮为关键中间体，合成了一系列2，4，5，7，9，10-六乙炔基芘。通过与4，5，9，10-四乙炔基芘和2，7-二乙炔基芘衍生物的比较，阐明了乙炔基的位置和数目对相应芘的物理化学性质的影响。所制备的带有苯部分的六乙炔基芘在溶液和/或凝聚相中通过π-π堆积自组装。
A series of 2,4,5,7,9,10-hexaethynylpyrenes was synthesized using 2,7,9,10-tetrabromopyrene-4,5-dione as the key intermediate. The effects of the position and number of the ethynyl groups on the physicochemical properties of the corresponding pyrenes were clarified by comparison with 4,5,9,10-tetraethynylpyrene and 2,7-diethynylpyrene derivatives. The prepared hexaethynylpyrenes that bear benzene moieties self-assemble via π–π stacking in solution and/or the condensed phase.
